VoidMob does not provide an unlimited data eSIM plan for South Korea.
Instead, VoidMob offers fixed data plans that include a specified data allowance for a limited validity period. For example, the South Korea 50 GB plans are valid for 30 days and are priced at $26.99 USD or $35.99 USD, while the China Korea Japan 60 GB plan is valid for 90 days and costs $71.99 USD. Choosing one of these fixed data plans may be more cost‑effective for most travelers, unless they anticipate very heavy data usage that would exceed the allotted data.
